I don't have accurate statistics on the total throughput. <BR>
<BR>
I know that my server deals with 26000 messages (8100 spam, 64 virus mails) on a weekday, has 263 mailboxes (several are multi-drop pop boxes). Message size total is 575MB (includes spam).<BR>
<BR>
Now this is the message size, not the throughput. POP3 access could double that (remove some spam, add protocol overhead) and relayed messages would also add to that (SMTP in -> SMTP out). I had 11,350 POP3 accesses at 1.5k per access (with no message to download) is another 18.3GB<BR>
<BR>
Based on this my estimate is that my mail server uses about 1.2GB per day.<BR>
